Description

Self-cooling magnetic pump Technical Field The utility model relates to the technical field of magnetic pumps, in particular to a self-cooling magnetic pump. Background In the technical field of fluid transmission, a magnetic pump is used as a non-leakage and non-contact liquid conveying device, and is widely applied to occasions requiring high-cleanliness or corrosive liquid transmission, such as chemical industry, medicine, electronics and the like. The traditional magnetic pump working principle relies on a motor to drive an outer magnetic rotor to rotate, and the outer magnetic rotor drives an inner magnetic rotor and an impeller connected with the inner magnetic rotor to synchronously rotate in a non-contact manner under the action of a strong magnetic field, so that effective extraction and transportation of liquid are realized. The design not only avoids the leakage problem of the traditional mechanical seal caused by friction, but also improves the operation reliability and safety of the pump. During operation of the magnetic pump, the extracted liquid enters a narrow gap between the spacer made of non-magnetic material and the inner magnetic rotor and submerges the inner magnetic rotor. The characteristic utilizes the heat conduction performance of the liquid to a certain extent, so that the liquid can absorb the heat generated by the isolation sleeve due to the electromagnetic effect in the extraction process, the self-cooling function of the magnetic pump is realized, the service life of the magnetic pump is effectively prolonged, and the working efficiency is improved. Although the liquid flow can take away a part of heat to have a certain natural cooling effect, the rotation of the inner magnetic rotor in the liquid adds additional friction resistance, which not only reduces the efficiency of the pump, but also can lead to energy loss and noise increase. More importantly, when the inner magnetic rotor surface material contacts the pumped liquid for a long time, especially when the inner magnetic rotor surface material is corrosive, the inner magnetic rotor surface material can be corroded, the structural integrity and the service life of the inner magnetic rotor surface material are affected, and finally the overall performance of the magnetic pump is reduced.
